Such needs and purposes will hereinafter more fully be described andpointed out.

The bottom part, or metal steering plate, will thus eliminate all dustand draft from the corners of double hung windows at meeting rails,where sashes meet parting strip on sides of jambs, while the upper part,or latching member, will securely interengage such windows in anydesired position.

With the further appliance of an independent :device, not described,shown, or claimed, herein, as it may consist of a simple hook, orsimilar apparatus, fastened to the sash, and adapted to engage recesses.01 notches in the frame, this invention will practically render suchWindows burglar-proof, and the combined adjustmentmay be to the effectthat no person will from outside lie able to enter, or operate thecombination-lock as thus described.

Said combination will furthermore ,on account of its specialconstructionact as a steering guide tor loose and rattlingwinbinationwith the former, I shall in this application confine mydescription and claims. to said improvements 1n WIDClOW latch and.

draft plates.

In a slightly modified form the latching member of my device may be usedinstead of the ordinary window clasp, as .I in this case use a specialtoot-plateas shown clearly in Fig. 6.

With the above and other objects in view,

at the same time forming an integral com this invention consists of thenovel features of constructlon, combination and arrangements of parts,hereinafter fully described, cla med, and illustrated in theaccompanying drawings iorming parts .of this specification, and in whichsimilar characters of reference indicate corresponding'parts in allviews, and in which;

Figu e 1 is a perspective View of my invention; Figs. 2 and .3illustrate the construction of the combined latch mechanism;

Fig. 4 is a top view of the combined device; Figs, 5 and 6 show mydevice in a modified form. Fig. 7 is a detail view of two latch members.

Referring more particularly to the drawings, 17 designates a fasteningmember formed integrally with the plate 10, the

latter indicates ametal plate adapted to be 1 fastened on top at oneflipper corner of the lower sash of a doublelmng window. Said plate isprovided with a substantially square, cutout portion 11 .to allow spacefor, and 03 ,111 a snug fitting with, the parting strip 15 .of thewindow This plate has a further reduced portion as shown at 12,providing suff cient space for the sash cord 16, for which purpose ithas at its base, been formed with a slight, inward curvature 13. Thisreduced portion further takes in space, as indicated at 14, in order topermit the passing-0f the sash pulley, when .the sh i op ned a d rai tthe t p of a window frame.

The said fiastening member 17 comprises a frame 18 side walls 19 and alever or nd e 20- To sa d le i p v ta ly engaged, in the manner shown, astop-member 21, and a release member 22. Said lever is turnaibly'seatedon an axle 23,, the latter being rigidly Supported by the walls19. It will be noticed that the members 21 and 22 have .a reenforcedbearing 241211; the section where the engagement with-the lever takesplace. Said lever connects with members 2land 22 by means of bifurcatedsections 25- formed on the latter and pivotally connected by means ofaxle pins .26. V
